Campaign Studio limits web requests and API calls to protect Campaign Studio
and the user. A web request takes place when known or unknown contacts visit a
website tracked by Campaign Studio. For more information on adding the
JavaScript to your website, review the Tracking Settings section of our tracking settings.
More visitors require more web requests. When your account has reached its
limit, Campaign Studio displays an error message. Campaign Studio computes the
total each second. If your account exceeds the limit in one second, you can
access your account seconds later. Your account operates as expected, meaning
marketing communication will still send and track.
While Campaign Studio doesn’t have a daily API Request limit, Campaign Studio
Cloud instances are limited by default to 70 requests per second. If you need
this changed, create a Support ticket.
